MAKING NETWORK CONNECTIONS

MDI-X port using straight-through cable. To connect between two switches/hubs that only have fixed MDI-X ports, the wiring crossover must be implemented in the cable - known as a crossover cable.

The RJ-45 ports on the switch base unit support automatic MDI/MDI-X operation, which means that they automatically detect the wiring in the link and configure as MDI or MDI-X accordingly. So for these ports, you can use standard straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, hubs, or routers). However, note that auto-negotiation must be enabled on these ports for automatic wiring configuration to function properly.

See Appendix B for further information on cabling.

Connecting to PCs, Servers, Hubs and Switches

Caution: Do not plug a phone jack connector into an RJ-45 port. This will damage the switch. Use only twisted-pair cables with RJ-45 connectors that conform to FCC standards.

1.Attach one end of a twisted-pair cable segment to the device’s RJ-45 connector.
